Welcome to Android Central! Which phone do you have, and what email app are you using? Was the email sent already, and you want to re-send it? You should be able to select the email, tap the menu button, and Forward it.
my phone is lg E612 & the app I'm using is just the app that came with the phone. I write the email while I'm offline, then when I go online, it won't send from my outbox
